Octoombas are an Octorock-like alien sub-species of Goomba in Super Mario Galaxy and Super Mario Galaxy 2. It was the sequel that revealed the enemy's name. They have the same basic shape as a Goomba, but resembles, as its name would suggest, an octopus. The Octoomba comes in three colors: blue, green, and red. The blue is the most basic, since it appears the most and only side-steps in a small area. In Super Mario Galaxy 2, it can shoot rocks whenever Mario or Luigi passes by. The green Octoombas are like the blue Octoombas, except they shoot 2 rocks in a row. The red Octoomba will go after Mario or Luigi, making them slightly more difficult to defeat. Both of them will shoot rocks towards Mario/Luigi from its octopus-like snout as an attack. Instead of replacing Goombas in the game, like the Strollin' Stu did in Super Mario Sunshine, the Octoomba fights along side the Goomba instead of taking their place.
